John, I guess I had thought this was covered in the FAQs, either Jo's or Max', but I'm not finding it. it certainly should be, as it is a multiple yart and has confused nearly everyone. it is not a random bug and the cause is well known. as Jazzo indicates just above, the cause is ALWAYS (well, unless you purposely preformat) a wide link (or url, as dr. bill would have it). the remedy is to shorten internal links (cut 'em after the first post number) or use Max' "make a shorter link" link (where is it Max?!) for external links.

since the width of any thread is determined by the width of the widest post in it, it's not always obvious where the problem lies....
